Come on in: Nuclear barrier less restrictive than expected in new cells
When it comes to the two basic types of cells, prokaryotes and eukaryotes, compartmentalization is everything. Prokaryotes are evolutionarily ancient cells that only have a membrane surrounding their outer boundary, while ...

Research suggests core nuclear pore elements shared by all eukaryotes
(PhysOrg.com) -- For perhaps 1.8 billion years after life first emerged on Earth, a sort of evolutionary writer’s block stalled the development of organisms more complicated than single cells. Then, a burst of experimental ...
